What should you know about primary prevention of hypertension?

Blood pressure can rise gradually without obvious symptoms, so prevention includes checking it even when you feel well. Family history, age and some medical conditions cannot be changed, but activity, food choices, alcohol intake, tobacco use, sleep and body weight can be addressed. Unrecognised or untreated hypertension can strain blood vessels and organs, including the heart, brain and kidneys.

Choose meals built around vegetables, fruit, beans, whole grains and unsalted foods, while limiting heavily processed items. Build regular movement into the week and break up long periods of sitting. Avoid tobacco and keep alcohol within local clinical advice. If weight is above a healthy range, gradual, supported changes can help. Ask a clinician how often to check your pressure and review medicines that may raise it. Managing sleep problems such as obstructive sleep apnoea also deserves attention.

Book an appointment if readings remain above the range your clinician has advised, or if you have risk factors such as kidney disease, obesity or sleep apnoea. Seek emergency help for very high readings accompanied by chest pain, severe breathlessness, weakness on one side, confusion, fainting or trouble speaking. These symptoms can signal an urgent problem affecting the heart or brain.

Ask what your personal blood pressure target is, which home monitor and technique are appropriate, and whether family history changes your check-up plan. You can also ask for help with salt reduction, activity, sleep or weight management.
